Reviews

Love this Bra

"I love everything about this sports bra! It fits perfectly, is super comfortable, supportive, and I really appreciate that it doesn’t have padding. For reference, I’m a 34D and ordered a medium."

Jamie P. (5/5)

New favorite!

"I love this bra! The fit is comfortable, flattering and functional for my training. It is a bra I could wear all day. I am usually between a small and a medium so I ordered a medium and it was too big. I exchanged for a small and it’s perfect. Will be ordering in more and would love to see a wider range of colors!"

Awesome Fit + Peace of Mind

"This is a fantastic bra. I don't dread workouts anymore because I feel supported and I don't have to worry about PFAS and endocrine disruptors. . . just good old fashioned sweat. 😉"

Kathryn L. (5/5)

Love the fabric

"I love that my shirts glide right over this smooth fabric. The band might be a smidge tight if you have wide ribs, but otherwise the fit is great and very supportive. I bought two sizes so that I can have a one a little looser for less intense activities."

Amber S. (5/5)

Best sports bra

"One of the best sports bras I’ve owned! Super comfy and light weight! Stays in place with intense workouts. One thing to note- there is no padding. Will be purchasing several more!"

Lauren H. (5/5)

Great Bra

"Love that the fabric feels like performance, love that there’s no pads, and love that it’s toxic chemical free!"

ciana j. (5/5)

Best Sports Bra

"The fit is amazing. I have not experienced any chafing whatsoever. Also have not noticed any lingering odor that most workout clothes have."

Rachel M. (5/5)

No-Tox Sports Bra

"I’ve had a hard time finding replacements for sports wear in my closet without harmful chemicals. I was happy when I tried this on. I would definitely order it again in another color!"

Abbie R. (5/5)

Racerback Bra

"I ordered size medium and it's a little small and tight, but will probably loosen up some over time."

Laura H. (3/5)

So comfortable!

"This bra is so soft, I’m a 34D and the medium fit perfectly"
